A device for drilling or boring openings, primarily deep openings, comprises a cutter head with guides, said head being equipped with a device for displacing the cutter in the radial direction from the drive. The input of the drive is connected via a control signal transmission circuit and a transducer to the output of a system for digital programming control (DPC). A sensor for checking variations in the wall thickness of the component, a sensor of the angle of rotation of the component, a sensor of the angle of rotation of the cutter head and a sensor for checking the wobbling of the component are connected to the DPC system. The drive of the device for displacing the cutter in the radial direction is in the form of a linear drive and is mounted on the cutter head The technical result is expressed in an increase in the accuracy of machining deep openings while ensuring that openings can be corrected during the process of machining the openings.
A device for drilling or boring holes comprising a cutter head with guides and a device for moving the cutter in a radial direction from a drive whose control system input is connected, via a converter, to an output of a computer control system, wherein a sensor for controlling variations in work piece wall thickness, a work piece rotation angle sensor, a cutter head rotation angle sensor, and a sensor for controlling work piece runout are added to the device for drilling or boring holes, and the drive of the device for moving the cutter in a radial direction is made in the form of a linear drive and installed on the cutter head.
